SEAMLESS DISPLAY OF VIDEO DURING CONNECTION SWITCHING

摘要

An electronic device uses one antenna to wirelessly communicate information with two different wireless networks via concurrent connections associated with different radio access technologies. More specifically, the electronic device may receive video via a first of the connections using a multicast communication protocol. In order to maintain the second connection, the electronic device may switch, for a time interval, from the first connection to the second connection during switching events. This switching can disrupt displayed content associated with the video. To prevent this disruption, in response to a trigger that warns of an upcoming switching event, the electronic device accesses a portion of the video in a buffer during the time interval associated with the switching event. When the communication circuit switches back to the first connection after the switching event, the electronic device reverts to the video communication using the multicast communication protocol.

主权项

1. An electronic device, comprising:
an antenna; a communication circuit, coupled to the antenna, configured to communicate information with a first wireless network using a first connection and a second wireless network using a second connection, wherein the first connection and the second connection are concurrent, wherein video is communicated to the electronic device via the first connection using a multicast communication protocol, and wherein the communication circuit is configured to switch, for a time interval, from the first connection to the second connection during switching events in order to maintain the second connection; a processor; and a memory that stores a program module, wherein the program module is configured to be executed by the processor to avoid disruption of displayed content associated with the video, the program module including:
instructions for receiving a trigger that warns of an upcoming switching event;instructions for accessing a portion of the video in a buffer in the memory to avoid the disruption of the displayed content associated with the video during the time interval associated with the switching event; andinstructions for reverting to the video communication using the multicast communication protocol when the communication circuit switches back to the first connection after the switching event.
